The Mariners have outrighted right-hander Christian Bergman, per a club announcement. That move clears another 40-man roster slot after the team lost righty Sam Gaviglio to a waiver claim earlier today; it’s also just one of the many transactions entered today by the ever-active M’s front office.

Righty David Phelps has returned to the 10-day DL due to an elbow impingement. He missed time earlier this month and has not looked himself of late. Indeed, Phelps has lost about two miles per hour on his average fastball as compared with the first four months of the season.

In more positive news relating to injuries, both outfielder Jarrod Dyson and righty Shae Simmons have returned from their own runs on the disabled list. The latter had been on the 60-day DL while working back from a flexor strain.

Catcher Mike Marjama was added to the 40-man roster and promoted to give the team another option behind the dish. The team also activated just-acquired righty Mike Leake.

With no limitations on the active roster, the M’s have also brought up a few players that were on optional assignment. Three right-handed pitchers — Dan Altavilla, Ryan Garton, and Andrew Moore — are on their way to help bolster the bullpen.

Here are the latest minor moves from around baseball, with the newest transactions at the top of the post…

The Astros have released righty Edison Frias, the Houston Chronicle’s Jake Kaplan reports (Twitter link). The 26-year-old Frias has some respectable numbers (4.07 ERA, 7.6 K/9, 2.71 K/BB rate) over 425 career innings in Houston’s farm system, though he has been hit hard at the Triple-A level this year, with a 7.71 ERA in 23 1/3 frames. Pitching in the hitter-friendly Pacific Coast League is likely a factor, though Frias hasn’t helped himself with a 5.8 BB/9 that is more than double his career average.

Earlier today

In a surprising development, the Reds announced Sunday that they’ve optioned left-hander Amir Garrett to Triple-A Louisville. Aside from one poor start on April 24, when the Brewers teed off on Garrett for nine earned runs on eight hits in 3 1/3 innings, the 25-year-old has pitched well enough to remain in the majors. The rookie surrendered two or fewer earned runs in his other six starts, all of which lasted at least six frames. All told, Garrett has recorded a 4.25 ERA, 7.0 K/9, 3.5 BB/9 and a 44.7 percent ground-ball rate in 36 innings. The Reds are entering a stretch in which they will only need four starters, which will give them an opportunity to manage Garrett’s workload, tweets Zach Buchanan of the Cincinnati Enquirer. Service time considerations may have also factored into this decision, as the Reds will only need to keep Garrett in the minors for about two weeks to control him through 2023 instead of 2022. For now, right-hander Barrett Astin is up from Triple-A to take Garrett’s place on the Reds’ roster.

The Padres have sold corner infielder/outfielder Jamie Romak’s contract to SK Wyverns of the Korea Baseball Organization, report Sung Min Kim of River Ave Blues and Dennis Lin of the San Diego Union-Tribune (Twitterlinks). Romak, a fourth-round pick of the Braves in 2003, saw brief major league action with the Dodgers in 2014 and the Diamondbacks in 2015. For the most part, the 31-year-old has played at lower levels, including a stint in the Japan Central League. Romak has spent the majority of his career at the Triple-A level, where he has slashed an impressive .271/.340/.516 line in 1,800 plate appearances.

The Mariners have made a few pitching changes, selecting Christian Bergman’s contract from Triple-A Tacoma, optioning Rob Whalen to Triple-A and moving Shae Simmons to the 60-day disabled list, per an announcement from general manager Jerry Dipoto. Bergman, who signed a minor league deal with the Mariners over the winter, spent 2010-16 with the Rockies organization. The swingman debuted in the majors in 2014 and has since posted a 5.79 ERA, 5.49 K/9 against 1.89 BB/9, and a 36.7 percent ground-ball rate in 147 2/3 innings. He got off to a strong start this year with Tacoma, tossing 29 innings from the Rainiers’ rotation and logging a 2.17 ERA. Simmons has been dealing with a right forearm strain since March, which has prevented the offseason trade acquisition from taking the mound this year. The Mariners acquired Simmons, a hard-throwing reliever, from the Braves in a January deal that also included Mallex Smith and Luiz Gohara.

The Rangers have purchased righty Austin Bibens-Dirkx’s contract from Triple-A Round Rock and optioned lefty Dario Alvarez in a corresponding move, according to the club. The 32-year-old Bibens-Dirkx has never pitched in the majors, having spent the first 11-plus years of his career in the minors with several teams, including Seattle, which selected him in the 16th round of the 2006 draft. Bibens-Dirkx owns a lifetime 5.16 ERA, 7.0 K/9 and 3.0 BB/9 in 383 2/3 Triple-A frames.

The Giants have informed 38-year-old shortstop Jimmy Rollins that he won’t make their roster, Andrew Baggarly of the East Bay Times was among those to report. San Francisco is now awaiting word on whether the longtime Phillie and 2007 NL MVP will accept a minor league assignment, per manager Bruce Bochy, but Baggarly notes that Rollins has a Thursday opt-out in his contract. This could conceivably be the end of the line for Rollins, who posted subpar seasons with the Dodgers and White Sox over the past two years. Chicago released him last June after a 41-game stint on the South Side, and he went on to ink a minors pact with the Giants in December.

More from the West divisions:

Angels utilityman Dustin Ackley will not opt out of his minor league deal, reports Pedro Moura of the Los Angeles Times (Twitter link). The former star prospect will instead go to Triple-A. Ackley, 29, is still recovering from the shoulder surgery he underwent as a Yankee last June; consequently, he hasn’t played the field this spring.

The Diamondbacks optioned Ketel Marte to Triple-A on Tuesday, meaning they’re primed to divide shortstop between Nick Ahmed and Chris Owings. Manager Torey Lovullo isn’t sure which of the two will get the lion’s share of playing time at short, though “he sort of intimated” Owings will be in the lineup everyday at various positions, according to Nick Piecoro of the Arizona Republic (Twitterlinks). Since debuting in 2013, Owings has seen action at both middle infield spots and center field.

It’s clear that the Dodgers will go with right-hander Brandon McCarthy over southpaw Alex Wood for the fifth spot in their rotation, writes Bill Plunkett of the Orange County Register. Wood seems resigned to the idea that he’s headed to the bullpen, observes Plunkett. While the 26-year-old Wood isn’t thrilled, he’s staying upbeat. “If I were anywhere else, I don’t think we’d be having this discussion,” he said. “You can look at it as the glass being half empty or glass half full. It’s one of those things where I’m excited because this is the best team I’ve ever been on. Whatever they want me to do, that’s where we’ll go.” Wood isn’t new to the bullpen, having totaled 35 of 112 career appearances as a reliever, and he could return to the rotation if the injury bug once again bites McCarthy. For now, it appears McCarthy will slot in behind Clayton Kershaw, Kenta Maeda, Rich Hill and Hyun-jin Ryu.

Mariners reliever Shae Simmons is progressing in his recovery from the forearm strain he suffered March 11, relays Bob Dutton of the Tacoma News Tribune. An MRI on Tuesday confirmed no ligament damage, but the righty will still go at least a few more days without throwing. As Dutton notes, the 26-year-old Simmons missed almost all of the previous two seasons with the Braves while recovering from Tommy John surgery, so the latest development is an encouraging one.

Rangers righty Tyson Ross threw his first live batting practice session today, Jeff Wilson of the Fort Worth Star-Telegram reports (Twitterlinks). The twenty pitch outing proceeded without issue, which leaves Ross on track for a somewhat more rapid timeline to return to MLB action than had been anticipated. Per Wilson, the bounceback candidate — who’s returning from thoracic outlet surgery — could be available as soon as early May. Texas will pay Ross $6MM this year, with up to $3MM available in incentives, in hopes that he can return to the form that made him one of the game’s more effective starters over the 2013-15 seasons.

With some questions in the rotation, especially early on, the Rangers may elect to carry a deep relief unit while relying on just three bench players, Evan Grant of the Dallas Morning News writes. The key to that arrangement is the versatility of Jurickson Profar and Ryan Rua, who could share time in left with Delino DeShields while also filling in wherever else they’re needed. Profar is primarily an infielder by trade, and that’s where Rua spent most of his minor-league career — though he has played mostly in the outfield in the majors.

It seems there’s reason for optimism for Athletics righty Sonny Gray, who was “very encouraged” after picking up the ball yesterday, as Susan Slusser of the San Francisco Chronicle reports on Twitter. Gray only made twenty throws from a distance of sixty feet and another fifteen from seventy-five feet, but that’s an important first step. He’ll repeat the exercise today as he seeks to speed up his return from a lat strain.

Mariners utilityman Shawn O’Malley needed an appendectomy yesterday, which will sideline him for around two weeks, as Bob Dutton of the Tacoma News Tribune reports. He and Taylor Motter are battling for a reserve role on the Opening Day roster, but the health issue could certainly move the needle. Thus far, Motter has the better spring stat line, with a .324/.435/.459 slash against O’Malley’s .278/.333/.278 mark. Both have options remaining and have reached the majors previously, though neither has a significant track record at the game’s highest level.

The Mariners also got some updates on a pair of righty relievers, Dutton adds on Twitter. Shae Simmons was able to play catch as he works through forearm issues, while Steve Cishek is scheduled for his first pen session tomorrow as he continues to progress from offseason hip surgery. It seems clear at this point that neither will be ready for Opening Day, though the deep Seattle unit should be able to bear the loss, and both could represent intriguing mid-season additions to the relief corps.

Dodgers star Corey Seager won’t appear in a game for the team at all this week, manager Dave Roberts told reporters (Twitterlinks via Andy McCullough of the L.A. Times). Roberts said over the weekend that Seager, who finished third in last season’s MVP voting thanks to a .308/.365/.512 batting line and strong glovework at short, is dealing with an “oblique-ish” injury. While there’s still time for Seager to ramp back up for the season, oblique issues have a tendency to linger. Seager hasn’t played since March 3 and now seemingly won’t get into action until the final third of the month. McCullough adds that lefty Scott Kazmir also isn’t likely to pitch in a game this week as he continues to tweak his delivery after leaving his most recent Cactus League outing due to tightness and limited mobility in his hip.

A few more injury issues worth keeping an eye on around the league…

David Price told Red Sox reporters that he’s not 100 percent certain exactly what the injury he’s facing is, but in fairly strange fashion, noted that he’d have opted for surgery if he were 22 or 23 years old (via Evan Drellich of the Boston Herald). “They said if I was 22 or 23, they’d have told me to go have surgery,” said Price. “…I’ve gone through this. This is something I feel like happens every spring training. It’s those first four to five weeks of spring training that I feel like I go through this every single year, and this year was just a little bit worse.” Pressed on the specifics of the injury Price stated that he’s not sure what precisely set off the alarm bells for doctors but added that his elbow feels good and offered no concern regarding his ulnar collateral ligament. There’s no timeline for his recovery, though Drellich notes that it’s looking likely that Price will be on the DL to open the season.

Brian MacPherson of the Providence Journal provides updates on a pair of mending Red Sox relievers (Twitterlinks). Setup man Tyler Thornburg, acquired in the trade that sent Travis Shaw to Milwaukee this winter, is slated to throw off a mound on Wednesday. Thornburg hasn’t appeared in a game since March 1 but appears to be nearing a return to action. As for last season’s setup acquisition, Carson Smith (who underwent Tommy John surgery before pitching in the regular season), he threw a 15-to-18 pitch bullpen session today, which marks his first mound work since undergoing his Tommy John procedure.

Nationals ace Max Scherzer voiced with confidence on Monday that he’ll be ready for Opening Day, per Jorge Castillo of the Washington Post. Scherzer, the reigning NL Cy Young winner, has been slowed by a stress fracture in his right ring finger but said plainly on Monday, “I’m gonna do it,” when asked about being ready for the start of the season. Manager Dusty Baker offered a similar take, stating that Scherzer is “a little bit behind but not as far behind as it looked like he was going to be at the beginning” of camp.

Mariners setup man Steve Cishek is all but certain to begin the season on the disabled list, per Bob Dutton of the Tacoma News Tribune. The 30-year-old side-armer had surgery to repair a torn labrum in his left hip last October and is still at least one week, if not two weeks, away from throwing off the mound, according to manager Scott Servais. “I think coming into this camp, it was no secret that we were projecting that he might start the season a little bit late,” said Servais.“We’re still on that schedule.”

Within that same piece, Dutton notes that the Mariners got better news on right-hander Tony Zych, who is already throwing off a mound and will face hitters in live BP this week. And in a second column, Dutton adds that the Mariners got positive news following an MRI on right-hander Shae Simmons. There’s no ligament damage in Simmons’ elbow, as the hard-thrower is instead dealing with a strained muscle in his forearm. He’ll be out for the next couple of days, but it seems that the former Brave has staved off any form of serious injury.

Former Diamondbacks executive and interim general manager Jerry Dipoto (now the GM of the Mariners) tells Nick Piecoro of the Arizona Republic that the biggest regrets of his tenure in Arizona are missed opportunities in the draft. “The (mistakes) that really gnaw at me and I still wake up thinking about are the ones in the draft,” says Dipoto. “Where you had a scout or multiple scouts in the room telling you, ‘This is the guy.’ You know, ‘We should take Chris Sale.’ We should have.” Of course, the D-backs were hardly alone in passing on Sale, who fell to 13th in the first round of the 2010 draft. Still, the D-backs’ selection of Texas A&M righty Barret Loux, who ultimately didn’t even sign due to medical reasons, stings Dipoto as a misstep to this day. Dipoto adds that he hopes he’s grown as an executive from his ealier days, when he’d “run renegade on a group” of scouts or let his voice “overwhelm the opinion of the group.”

More from the game’s Western divisions…

Mariners righty Shae Simmons exited today’s Cactus League game with the trainer, tweets MLB.com’s Greg Johns. While there’s no word on the specifics of the injury just yet, that’s a troubling scene for the newly acquired flame-thrower, who has already seen one season of his career wiped out due to Tommy John surgery. Simmons is competing for one of the final spots in the Seattle ’pen and, prior to 2015 Tommy John surgery, flashed quite a bit of potential in the Atlanta relief corps. The 2014 season saw Simmons rattle off 21 2/3 innings of 2.91 ERA ball with a 23-to-11 K/BB ratio.

The Rockies have been without catcher Tony Wolters since March 5 due to a hyperextended right elbow that he suffered on a swing, but he could return to the field on either Sunday or Monday, tweets MLB.com’s Thomas Harding. The 24-year-old Wolters hit .259/.327/.395 in 230 plate appearances as a rookie last season and drew excellent marks for his pitch-framing skills. He’s expected to split time behind the dish with fellow youngster Tom Murphy in 2017 as half of the Rockies’ primary catching tandem.

Dodgers outfielder Andrew Tolestells J.P. Hoornstra of the Southern California News Group that while he knew little to nothing of sabermetrics a year ago, his newfound fascination with modern metrics aided him in his rise to the Majors last season. Toles began teaching himself the new concepts on Fangraphs and admits that they changed the way he evaluated himself. “I think that’s it,” the 24-year-old said.“You don’t look at batting average, home runs, all that.” Toles cited director of player development Gabe Kapler and the Dodgers’ general willingness to break down exactly what they’re looking for as driving factors behind his embracing of advanced metrics and said that ultimately, the advice he received paid off. “I just pretty much did what they told me to do. I listened.”

The 20-year-old Gohara has only reached the Class A level, but is considered a high-quality pitching prospect. He worked to a 1.81 ERA over 69 2/3 total minor league frames in 2016, with 10.5 K/9 against 3.0 BB/9. MLB.com rated him Seattle’s fifth-best prospect, while Baseball America placed him third among the organization’s pre-MLB assets.

A rare Brazilian pitching prospect, Gohara impresses with a mid-nineties heater, promising slider, and still-developing change that give him the promise of a useful three-pitch mix that could work in a starting role at the game’s highest level.

Burrows also checked in on MLB.com’s ranking of the M’s prospects, placing 25th. The collegiate closer is a two-pitch hurler who was taken in the fourth round of the 2016 draft. He showed well at the low-A level in his first taste of professional ball, allowing just seven earned runs with 37 strikeouts against 11 walks over his 24 2/3 innings. The 22-year-old figures to move rather quickly through the system given his collegiate pedigree.

For the Mariners, Smith represents yet another fleet-footed outfielder. He’s still optionable, and may not have much daylight to crack the MLB roster to start the 2016 season, but could figure as a near-term piece who also comes with five full seasons of control. Smith had been viewed as a key prospect for the Braves, but was somewhat expendable with the team locking up Ender Inciarte for the foreseeable future and fellow youngster Dustin Peterson also rising through the system.

Smith, 23, missed time last year with a thumb injury, but got his first taste of the big leagues in a fairly extended stretch. Over 215 plate appearances, he slashed .238/.316/.365 and swiped 16 bases while drawing strong defensive ratings. He has long been a major stolen-base threat in the minors, and could yet turn into a semi-regular major leaguer if he’s able to drive up his batting average. Smith posted a roughly average .302 BABIP last year, but has traditionally carried much higher marks in the minors thanks to his speed.

The 26-year-old Simmons, meanwhile, comes with four years of remaining control. He has thrown 28 1/3 total major league innings, wrapped around a Tommy John procedure, with a 2.54 ERA and 8.3 K/9 against 3.5 BB/9. The high-octane reliever also showed well at Triple-A in 2016 and has a history of lofty strikeout totals in the minors, though he has also struggled at times with command.

Adding two 40-man players led to the move to bump Martin, a 27-year-old who has seen action in each of the past two major league seasons with three organizations (including the Braves, Athletics, and Mariners). He was hit hard in his first go-round, but posted a 3.86 ERA over 25 2/3 innings last year. Still, Martin managed only 15 strikeouts to go with nine walks while surrendering five long balls in that stretch. He was much better at Triple-A, where he worked mostly as a starter. At the highest level of the minors in 2016, Martin posted a 3.62 ERA with 9.0 K/9 and 2.6 BB/9 across 114 1/3 frames.

The Rockies have placed outfielder Gerardo Parra on the 15-day disabled list due to a high ankle sprain, reports MLB.com’s Thomas Harding (via Twitter). Parra will be in a walking boot for the next week, but there’s no word beyond that on the length of time the first-year Rox outfielder will miss. Parra, 29, is hitting .263 and showing solid pop (.160 ISO), but he’s drawn just four walks this season (one intentional), which has resulted in a 274 OBP — the ninth-lowest in baseball among qualified hitters. A corresponding move for Parra’s absence hasn’t been announced, but the Rockies have Brandon Barnes, Rafael Ynoa and Raimel Tapia as minor league outfield options on the 40-man roster.

A few more injury situations worth monitoring…

Athletics lefty Rich Hill is still about a week away from throwing off a mound, tweets Susan Slusser of the San Francisco Chronicle. With his last outing having come on May 29, it seems likely that Hill will need to make at least one minor league rehab start, which could push his return back into late June or early July depending on the exact timing of his ability to throw off a mound.

MLB.com’s Mark Bowman writes that Braves right-hander Shae Simmons, who is recovering from 2015 Tommy John surgery, still doesn’t have a target date to return to the Atlanta bullpen after a pair of setbacks in his rehab. Simmons has had two bouts of shoulder discomfort, and while an MRI has revealed that the shoulder is structurally sound, he’s been diagnosed with tendinitis in his right lat muscle. The 25-year-old Simmons last pitched for the Braves in 2014 when he logged a 2.91 ERA with a 23-to-11 K/BB ratio in 21 2/3 innings.

Right-hander Chad Billingsley acknowledged yesterday in an interview with Bruce Hefflinger of the Crescent-News that his elbow injuries may have brought his career to an end. Per Billingsley, doctors told him at the end of the season to rest his arm for seven months, but that time frame has passed and he’s still unable to throw a ball at more than 50 to 60 percent. The concern with ramping up his intensity would be that it could lead to a torn flexor tendon. “If a tendon tore it would be total reconstruction surgery,” Billingsley explained. “If that happens you start flirting with everyday life. But I’ve not totally given up. Most likely it’s career ending. The doctors don’t know anybody that has come back from it. If I do come back, it will most likely be out of the bullpen in some kind of short relief.” Billingsley pitched 37 innings for the Phillies last season but had his season cut short by a flexor strain. He also had Tommy John surgery in 2013 and a second elbow operation in 2014.

Braves president of baseball operations John Hart and general manager John Coppolella addressed the media today in the wake of the regular season’s completion and discussed a number of roster-related topics heading into the winter. Here’s a rundown of some highlights, courtesy of the Atlanta Journal-Constitution’s David O’Brien and MLB.com’s Mark Bowman …

Fixing the bullpen will be the team’s top priority this offseason, according to Hart, who adds that his secondary and tertiary priorities will be supplementing the offense and determining if there’s a need to make an addition that would upgrade the team’s starting pitching. The third goal listed will depend specifically on the health of presently injured starters Mike Minor, Manny Banuelos and Mike Foltynewicz, he added.

In the team’s initial talks with the Dodgers regarding Hector Olivera, Los Angeles initially asked for Andrelton Simmons to be included in the deal — a notion which the Braves quickly shot down.

Right-handed reliever Chris Withrow, who also came to the Braves in a recent trade, is expected to be ready for Spring Training 2016, per Hart. Another Tommy John victim, Shae Simmons, likely won’t be ready to join the Braves’ bullpen until sometime in May. Speaking generally, Coppolella noted the potential for significant improvement in 2016 simply by way of getting injured players back to full health. While the duo admitted that a 100-win team isn’t going to materialize next season, the expectation is a better record than the 67-95 mark with which they finished the season.

Though many reports have linked the Braves to acquiring young catching help this season, the team still “loves” Christian Bethancourt’s skills behind the dish and consider him a part of the future plans. That said, the Braves still hope to re-sign A.J. Pierzynski, though they fear that an American League club that could offer some additional at-bats at designated hitter might swoop in and sign the veteran backstop.

The Braves will head into 2016 planning on Minor being healthy enough to return to the rotation. That seemingly rules out any possibility that the club would look to non-tender Minor following a lost season due to shoulder surgery. Minor won an arbitration hearing against the Braves last offseason and was awarded a $5.6MM salary. His pay can’t be cut any more than 20 percent via the arb process, and the more likely scenario would be that he simply agrees to an identical salary for the 2016 season.

The Braves have announced that right-hander Shae Simmons underwent Tommy John surgery today and will miss the 2015 season as he rehabs from the procedure.

Simmons, 24, surfaced with the Braves in late May and enjoyed a very strong run through the end of July, but a sore shoulder cost him the final two months of the season. While healthy, the former 22nd-round pick notched a 2.91 ERA with 23 strikeouts against 11 walks in 21 2/3 innings. He allowed just one home run and posted an excellent 52.8 percent ground-ball rate to go along with an average fastball velocity of 94.9 mph.

The news continues a run of bad luck the Braves (and the entire league, in a more general sense) have had with Tommy John surgery over the past year. Last spring, Atlanta lost both Brandon Beachy and Kris Medlen to torn ulnar collateral ligaments, essentially wiping out 40 percent of their projected starting rotation. That led to the signing of both Ervin Santana and Aaron Harang, who performed admirably in their stead.

As MLB.com’s Mark Bowman tweets, the Braves say that Simmons began complaining of elbow discomfort last week. That may very well explain some of the team’s motivation for bringing in a vast array of experienced right-handers over the past week. Atlanta has added Jose Veras, Todd Coffey and Matt Capps on minor league pacts over the past three days, each of whom will be in Spring Training in hopes of securing a spot in the bullpen.
